The AT76C112 is a highly integrated solution for digital camera and image playback devices. It combines a number of functions that are required for implementing such devices. • Image data acquisition from CMOS imagers • Image display • Image processing and image storing • Overall system management • Control of general-purpose I/O functions • Data communication • Control of user functions • On-screen display It also provides a large number of interfaces that allow equipment manufacturers to directly access a variety of devices that may be present in a digital camera or image playback system. • Communication with PCs • Communication with Flash cards • Serial communication ports for controlling other devices in the system The design is based on an ARM® microprocessor that controls the entire chip. A number of hardware resources, controlled by ARM, perform digital imaging functions such as JPEG coding/decoding, image resizing, and DMA access to SDRAM. All these computational- intensive functions are implemented in hardware which can be programmed according to user specifications, thus allowing ARM to be free for other user-defined functions.
